Patent

CA 2636986

A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider (10) that is normally mounted on the rig floor is supported by a table (12) elevated above the rig floor. Supporting the spider on an elevated table provides personnel with access to a portion of the length of the pipe string below the elevated spider and above the rig floor for applying a fastener to secure the control line (31) to the pipe string. The control line is supplied from above the spider and is positioned by a control line guide (42) supported on the spider or a sleeve (40) to pass through the spider outside the path of the pipe gripping members, such as slips (24) .

L'invention concerne un procédé et un appareil destinés à installer des lignes de commande et un tuyau dans un puits. L'araignée de support du tuyau (10), qui est normalement montée sur le plancher de l'installation de forage, est posée sur une table (12) élevée au-dessus du plancher de l'installation de forage. Le fait de poser l'araignée sur une table élevée procure au personnel un accès à une partie de la longueur du train de tiges en dessous de l'araignée élevée et au-dessus du plancher de l'installation de forage de manière à appliquer un dispositif de blocage pour fixer la ligne de commande (31) au train de tiges. La ligne de commande est amenée depuis au-dessus de l'araignée et est positionnée par un guide de ligne de commande (42) posé sur l'araignée ou un manchon (40) de manière à passer à travers l'araignée en dehors du passage des éléments de préhension du tuyau, tels que des éléments coulissants (24).
